Is your feature request related to a problem? Please describe: I get lost trying to navigate my previous chats.

Describe the solution you'd like:
I use openwebui a lot, it's great! But I end up creating a lot of chats and some of those I reference back to at some point. It would be nice to better group previous chats, whether it was a folder I could add chats to or better yet save chats pertaining to a certain model used. For example I have a model dedicated for assisting me with help desk tickets, every time i selected this model, it would be awesome to see just chats for that model be listed on the sidebar.
